My husband and I have a 12 year old son whom has always been very demanding since birth, always wanting attention, doing naughty things and constantly seems to break things not on purpose just due to sheer carelessness. We tried to keep him stimulated with lots of attention and love, reading to him, swimming lessons, kinder gym musical classes etc. Now that he is 12 and twice my size he constantly argues with me and at times uses his size to push me out the way,swear at me and threaten me. He says he wishes I was dead and other nasty things. He seems happy at his new school and has friends. Once he is in a negative mood it can take up to 10 days for him to come out of it. What is wrong with him ? Could it be ADD ? He is an Aquarian. I am very patient but after 4-5 days of this behaviour I am pushed to my limits. We thought all children were like this until our next child was born whom is a reasonably easy child and is now 7.
